Thank you everybody. I feel truly honoured, but this was a community project and I'm only part of that community. I learned a lot on the way to my final design: Larry showing his designs that didn't satisfy him, but gave me an idea of what he was after; Shapeshifter's straightforward method of turning a triangle into a kaleidoscopic image; Rik and his humour in designing the cetificate; and other contributions along the way.

In fact what I'm trying to say is that I really love this forum because of the people involved: if you need help, you will get it (and fast !), if you need a laugh you can get that too.
